DND Does not divert to Voicemail
When I switch on Do Not Disturb on my iPhone, I had thought it would auto-divert to my voicemail message. However, not so - a voice says 'the person you are trying to contact is not available - leave a text message'. I want it to divert straight to voicemail. Can I do that? Is this an iPhone thing or is it a carrier setting?
